Walmart carries a wide selection of clear plastic cups for cold drinks, desserts, and more.

• Sizes: from mini portion and shot sizes (around 1–2 oz) to everyday 5, 9, 16, and 18 oz, up to larger to-go styles (12–24 oz).
• Styles: standard cups, sets paired with flat or dome lids, and cup‑and‑lid combo packs.
• Materials: commonly clear PET or similar plastics designed for cold beverages.
• Packs: bulk counts for events and smaller packs for everyday use.

You can shop online and filter by size, count, or lid options, then choose Pickup or Delivery where available. If you need hot beverage cups, look for items specifically labeled for hot liquids, since most clear PET cups are intended for cold use.

Picking the size comes down to how much ice you like and what you’re serving.

• Iced coffee or tea: 16–20 oz works well for a typical medium with plenty of ice.
• Iced espresso drinks: 12–16 oz helps keep the flavor focused without watering down.
• Smoothies or milkshakes: 16–24 oz leaves room for thicker blends and toppings.
• Kids’ drinks or tastings: 5–9 oz helps minimize waste.

Consider your lid choice too: dome lids make space for whipped cream or fruit; flat lids save storage space. Capacities can vary by supplier, so check product details and reviews. Sizing up slightly can reduce refills at gatherings, but preferences differ by drink and ice level.

They go by a few different names on Walmart.com, depending on use and size.

• Clear plastic cups or cold cups for everyday beverages.
• PET cups when the material is specified for clarity and cold use.
• Dessert or parfait cups when paired with dome lids for toppings.
• Portion cups for sauces, samples, or small sides (about 2–5 oz).
• Mini shot cups for very small servings (often around 1 oz).

Names can vary by supplier, so it helps to scan titles for the ounce size, “with lids” if you need them, and material notes like PET. For hot beverages, choose products labeled for hot use rather than clear PET cold cups.

You’ll find clear plastic cup sets that include lids—and some include straws.

• Flat lids: streamlined, often with a cross‑cut for straw insertion.
• Dome lids: extra headroom for whipped cream, fruit, or parfait layers.
• Strawless sip lids: a convenient on‑the‑go option for cold drinks.

Check that the lid diameter matches the cup size; many lines use shared lid sizes across certain ounces, but not all do. Product titles often say “cup and lid combo” or “with lids and straws.” Most clear PET sets are intended for cold beverages. You can filter for lid style online and choose Pickup or Delivery where available, depending on your location.

A quick planning approach can help you estimate what you need.

1. Estimate per guest: plan on 2–3 cups per person for casual events; add more if you’ll offer multiple drink types.
2. Match sizes: 16–20 oz for main beverages; 5–9 oz for kids, tastings, or desserts.
3. Add extras: build in roughly 10–15% extra for spills and last‑minute guests.
4. Consider lids: flat or dome lids can help reduce spills in busy spaces.

For example, a 20‑person get‑together might use about 50–60 clear cups, depending on refills and drink variety. Buying a larger pack can reduce mid‑event runs, but optimal quantities vary by menu and guest preferences. Pickup and Delivery may be available to streamline prep.
